Android SMS Gateway — send & receive SMS via API
Install one app on an Android phone and it becomes a full, self-hosted SMS gateway: your software sends text messages with a single REST call and receives replies as signed webhooks — all over your own SIM and number.
A real phone, controlled by your code
Most messaging providers route your texts through a shared aggregator, a rented sender ID, or a shortcode you never really own. An Android SMS gateway flips that around. The phone in your hand — with the SIM you already pay for — does the sending and receiving, and a thin REST layer lets any system drive it. You keep your number, your delivery path, and your costs, while your applications gain a programmable SMS channel.
Because the gateway runs on a device you control, there is no per-message aggregator markup and no third party sitting between you and your customers. The app maintains a secure link to the service, accepts send requests, dispatches them through the handset's own SMS stack, and reports delivery status back.
Send with one REST call
Sending is a single authenticated HTTPS request — no SDK to install, no proprietary client library. Your ERP, CRM, helpdesk or accounting system simply posts the recipient and the text, and the paired phone sends it within seconds. Every message gets an ID you can use to track its delivery state, so your application always knows what happened.
Receive replies automatically
Inbound texts are where a gateway earns its keep. When a customer replies, the app captures the message and pushes it to an endpoint you choose, signed with HMAC so you can verify it genuinely came from your gateway. That turns SMS into a two-way channel your software can act on — log it, route it, auto-answer it, or open a ticket.
Where teams use it
- Order, dispatch and delivery alerts fired straight from business events.
- One-time passcodes and verification messages sent from your own number.
- Two-way support and sales conversations driven from existing tools.
- Reminders, confirmations and follow-ups scheduled by your back office.
The full request and response shapes — sending, delivery tracking, devices and webhooks — are in the REST API reference. When you are ready to wire it up, the quickstart walks you from install to first message in about five minutes.
